Here's a really useless datapoint for you :)

We have about 12,000 students in our dorms.  Because we force students to
register their computers via the Web and the XBox/PS2's don't appear to have
web browsers, we have somewhat of a handle on who many are in use on campus.
We've generally average about four or five new XBox/PS2's per month over
the past year but we registered 12 in November (all were on or after 11/9).
We're also tracking down another five to ten hosts that we believe are also 
XBox/PS2s.  There were three more registered so far in December.  Obviously, 
this doesn't include any gaming systems that sit behind NAT-boxes.

Overall, we typically move around 190/230bbps inbound/outbound from our campus
and we've seen no real noticable change in our bandwidth.  We do have a few 
peer-to-peer limiters in the network, so its also possible that the gaming 
systems are being caught in there.

I doubt Halo 2 would show anything on most stats as its relatively low
bandwidth. 
However, Half-Life 2 I believe did for some larger residential operators.

Many moons ago when Doom 2 was released we busied out modems so we could
get more bandwidth over to the US to get it downloaded quicker though.

Peering best practices advice needed.

2004-12-08 Thread Rolo Tomassi
Hi all,
Please forgive the simplistic nature of the query..
Basically my company is multi-homed with 2 different providers in the UK, 
and advertising a /18. Now some colleaguges in another part of the world 
want to break that /18 into two /19's and advertise one /19 and we advertise 
the other. This is fine, however we are NOT running IBGP in the core, 
therefore the UK customers in the /19 will not be able to reach the other 
/19 as there would be a loop detected through EBGP.

Now someone mentioned that we could use AS-LOOP-IN feature which will 
overcome this problem and allow us to route to each other via EBGP. I really 
think this is a bad idea but until we get an internal link - I dont see a 
way forward. So... anyone doing this currently in their network or have any 
"best practices" way round this. I want our company to be good Netizens but 
still be able to pass traffic between the 2 /19's.

Any help would be greatly appreciated.

This will only work if you have separate ASNs, which would be my 
suggested solution.  In fact, even if you announce the /18 + both /19s, 
as long as each site as a separate ASN, it will work.

If they must have the same ASN for some reason, have your upstreams 
send you default route as well as a full table.  You will not see the 
"other" /19, but you will send traffic to the upstream because of the 
default and they will route it properly.

Now someone mentioned that we could use AS-LOOP-IN feature which will 
overcome this problem and allow us to route to each other via EBGP. I

I've never used AS-LOOP-IN.  Sorry. :(
But I have used the above solution (and static defaults), and it works 
fine.

Re: Peering best practices advice needed.

2004-12-08 Thread Graham Blake
Hi there,
If I understand your predicament correctly, our company has a similar 
situation. We have two locations from which we need to advertise routes 
from our AS, but our internal link between these two locations is a very 
high cost satellite link. This means we can not afford to advertise our 
whole IP allocation equally from both locations.

We have a /19 allocated, and we advertise both the /19 from each location, 
and the more specific /20 particular to each location. To circumvent the 
loop detection, we use the hidden Cisco command, neighbour x.x.x.x allow-as 
in. This allows each location to accept the remote's advertised /20 to be 
inserted into the routing table. Should connectivity ever be lost across 
the public networks in between, there is a higher cost static route over 
the satellite link.

Perhaps in a more complex and more meshed AS, this loop dodging would be a 
bad thing(tm). In our simple two location, semi-discontiguous network 
layout, it has been a problem-free solution. Hope this helps in some way.

This is lost in the noise of P2P traffic, which is the big bandwidth
eater by far.

I note that the story is essentially based around statements made by
Sandvine. They aren't saying that the amount of broadband traffic is
going to increase significantly because of online gaming; they're saying
that broadband networks need to prioritize and QoS traffic from gamers,
as more people game online.

And oddly enough, Sandvine offers a box that does this! :-) They're
jumping on the press coverage of Halo 2 to try and raise awareness of
their product line. Not that what's being said doesn't have merit, but
it's definately a PR push, and definately not a "End of the net
predicted, film at 11" moment.

The source cited in both articles is the same: Sandvine.
These guys are not unbiased.   They make bandwidth-limiting devices.

They proffer their boxes to cable/dsl operators that are trying to
avoid spending money on needed infrastructure improvements.

ASN and Peering Problem

2004-12-08 Thread Adi Linden

We currently have two /19 that we advertise on a single ASN. A client
would like to obtain /23 or /22 from us. This is not a problem, except
that their primary internet provider is someone else, other than us.
I think that they would need to have their own ASN to advertise their
portion of our ip space to their peers.

My question is, should we provide the ASN or should they apply for an ASN?
What is the minimum block considered routable, is it reasaonable to
advertise a /23 on its own ASN?

Are there any other solutions I haven't thought of?

Thanks,
Adi


Little brother of sitefinder

2004-12-08 Thread Christopher X. Candreva


It has just come to my attention that NetSol is now assigning a CNAME record 
of resalehost.networksolutions.com to all expired domains. This is so the 
web site will come up with a "This domain expired on this data, click here 
to renew." page.

resalehost.networksolutions.com has IP 216.168.224.53, doesn't listen on 
port 25, and has no MX record. The upshot is, mail to expired domains, 
instead of being rejected outright in the SMTP dialog, sits in our queue for 
5 days. Users don't know right away that mail isn't getting through.

This isn't quite on the same level as Sitefinder, but it's the same mindset, 
make a change without examining the impact.

The operational impact has been support time spent finding out why mail has 
supposedly disappeared, and/or is sitting in our queue.

Is this new, or have I had my head in the sand ?

Many people do /24s.  There is no real difference between a /24 and /23 
in most people's filters.  A /20 may or may not get them more 
reachability, but as long as you accept their /23 and announce the

Re: ASN and Peering Problem

Assuming that this is in North America (this is NAnog, afterall), they
should probably apply to ARIN for both the /22 (if they can justify that
much space) and the ASN, or, get the ASN from ARIN and the space from you.
As of policy 2002-3, ARIN will assign /22s to end users that have need of
a unique routing policy and meet other tests necessary for such an 
assignment.
These are the same tests you would be required to hold them to for you to
assign them a PA /22.

[Fwd: zone transfers, a spammer's dream?]

2004-12-08 Thread Gadi Evron

Hello all,

while doing some experiments with dig using a .fm domain I made a small
typo. Much to my surprise the whole fm zone was transferable by anyone.
It's obvious this is a fabulous source for dictionary spammers who just
mail to generic addresses at as much domains as they can possibly find.
([EMAIL PROTECTED], [EMAIL PROTECTED], ...)

Intrigued by the .fm zone, I did a quick scan to see which other top
level domains allowed zone transfers. It was no surprise to me that some
small zones of developing countries were open, but one top level domain
immediately caught my eye: getting the complete .ca zone (Canada), 48 Mb
in total, serving 471.686 domains is as easy as doing 'dig axfr ca
@ca01.cira.ca.'

Some zones weren't transferable at the master nameservers, but were
transferable at slave servers.

3 to get the number of domains, as this lists multiple name servers per
domain)

than 24 domains getting on yet another spam list, but why Canada makes
nearly half a million domains as easy to grab as this really is a
mystery to me.

What do you think?

RE: Peering best practices advice needed.

2004-12-08 Thread Ejay Hire

Hello.

Three options.

1.  Acquire a second ASN, and announce each site's /19 from
a different asn.

2.  Announce each locations /19 from it's respective
location, using the same asn.
Use the cisco BGP command Allow-as-in to permit each AS to
hear the remote site's network advertisement.

3.  If the remote site will not be multihomed, ask their ISP
to announce the /19 for you.

My gut says that if you are advertising a block in the
territory of another RIR, your irr entries will need to be
correct to save filtering issues.

Good Luck,
Ejay

RE: ASN and Peering Problem

2004-12-08 Thread Ejay Hire

If I understand, they would like you and the other provider
to both announce the IP space, from your respective ASN's. 

Real-world, this will work, but causes an "inconsistent
origin" bgp error.
